[0020] Furthermore: In order to facilitate the rapid flipping and reinforcement of the welded object, an inner polygonal rotating shaft 6 is provided on both sides of the welding table 1 through a bearing rotation, and one end of the inner polygonal rotating shaft 6 extends to the inside of the welding table 1, and the two inner polygonal rotating shafts 6 are opposite to each other and are located inside the welding table 1 and are fixedly connected to a mounting frame 7. A plurality of first electric telescopic rods 8 are fixedly provided around the inner wall of the mounting frame 7, and the extended end of the first electric telescopic rod 8 is fixedly connected to a clamping frame 9, and a centering locking mechanism 11 is provided on the clamping frame 9. A flipping reinforcement mechanism 10 is provided between the inner polygonal rotating shaft 6, the mounting frame 7 and the welding table 1. The flipping reinforcement mechanism 10 includes a polygonal drive shaft 105, and the polygonal drive shaft 105 is slidingly arranged. Inside the inner polygonal rotating shaft 6, a first spring 106 is fixedly arranged between the polygonal driving shaft 105 and the inner polygonal rotating shaft 6, and one end of the polygonal driving shaft 105 is fixedly connected to a reinforcement frame 107. The front and rear sides of both sides of the welding table 1 are provided with double-jointed slides 101 for use with the reinforcement frame 107. The inner sliding connection of the double-jointed slide 101 is provided with a reinforcement plate 102, and a second spring 103 is fixedly connected between the reinforcement plate 102 and the double-jointed slide 101. The front and rear sides of both sides of the mounting frame 7 are provided with reinforcement slots 104 for use with the reinforcement plate 102. As a detailed explanation: the first spring 106 is a high-strength spring, and the strength of the first spring 106 is greater than that of the second spring 103.

[0021] Among them: in order to facilitate the centering of the welded object inside the clamping frame 9, the centering locking mechanism 11 includes a bidirectional threaded rod 112, which is rotatably arranged on the surface of the clamping frame 9 through a bearing, and two bidirectional threaded rods 112 are symmetrically arranged, and the top and bottom of the surface of the bidirectional threaded rod 112 are threadedly connected with a threaded sleeve 113, and the surface of the threaded sleeve 113 is fixedly connected with a clamping block 111 through a bracket, and one end of the clamping block 111 slides and extends to the inside of the clamping frame 9.

[0022] During use, the operator places the plates to be welded into the clamping frame 9 in sequence, then screws the bidirectional threaded rod 112, prompting the two threaded sleeves 113 to respectively drive the two clamping blocks 111 to synchronously clamp the plates in the center, then drives the first electric telescopic rod 8 to prompt the clamping frame 9 to carry the plates for welding, then drives the longitudinal drive mechanism 3 and the transverse drive mechanism 5 to adjust the welding position of the laser welding gun 4 to weld the seam;

[0023] When welding is required on the bottom surface of the plate, the operator pulls the reinforcement frame 107 to pull the reinforcement frame 107 out of the double-jointed slide 101. The movement of the reinforcement frame 107 synchronously drives the polygonal drive shaft 105 to move. The polygonal drive shaft 105 synchronously tightens the first spring 106 to store energy. After the reinforcement frame 107 is pulled out, the reinforcement plate 102 will reset itself through the second spring 103 due to the loss of pressure, and will be out of the limit fit with the reinforcement slot 104. Then, the reinforcement frame 107 is rotated to 180° and release the reinforcement frame 107. The reinforcement frame 107 is released through the elastic reset of the polygonal drive shaft 105 and the first spring 106, prompting the reinforcement frame 107 to re-match with the double-jointed slide groove 101. When the reinforcement frame 107 is inserted into the double-jointed slide groove 101, it will simultaneously press the reinforcement plate 102. Since the strength of the second spring 103 is less than that of the first spring 106, the reinforcement plate 102 is passively inserted into the reinforcement slot 104, and the flip surface of the mounting frame 7 is reinforced simultaneously.
